RHOC's Shannon Beador may not get full custody of her children following a boozy night in Mexico

Real Housewives of Orange County star Shannon Beador is about to lock heads with her estranged husband David Beador. It seems that the reality star's ex-husband is challenging her previous requests for child support, child custody, and spousal support that Shannon had filed for back in December.

The reports, which were obtained by E! News, state that Shannon is "not fostering or encouraging a healthy father-child relationship." David is pushing for joint legal custody of his children, with "50% physical custody" of the children.

The father-of-three also alleged that Shannon is enabling negative sentiments about her ex-partner with their youngest daughters. David added: "While the children (Stella and Adeline) have resided with Shannon, since separation, the children, on several occasions have refused to talk or see me."

David requested the court to look into the matter by continuing his claim, stating: "This behavior has been tolerated in Shannon's home and is not in the best interests of the children. I have requested they spend nights with me however they have expressed concerns for their mother in this event."

David also slams his ex-wife's career, citing how the reality star has not exactly been candid about work ethics and schedule. He said: "Shannon's employment encourages excess drinking and extended travel to which Shannon has chosen not to inform me and make accommodations for the kids to stay with me while she is away."

It looks like David's wishes might just come true. Shannon, along with fellow RHOC stars Vicki Gunvalson and Tamra Judge had a banging vacation in Puerto Vallarta, Mexico. The soon-to-be-single RHOC housewife was partying like there's no tomorrow. Obviously a little tipsy, the reality star can be seen dancing on the bar with Tamara to Rod Stewart's 'Do Ya Think I'm Sexy'.
